Gtkguitune

Guitar (and other instruments) tuner for GTK+2

gtkguitune is a program for tuning guitars and other instruments. Rather than using FFT like many programs, it counts the number of triggerings between two trigger levels in a certain amount of time, which tends to be more accurate for instrument tuning while requiring less processing than FFT.
